OB/Gyn Imaging and procedures Flashcards
Types of breast imaging
- diagnostic mammogram: lump, skin changes, abnormal screening
- ultrasound: differentiates solid vs cystic; 1st line imaging <40 y.o
*MRI: women at high risk; post cancer diagnosis
what are breast procedures?
Fine needle aspiration: smaller mass
Core needle biopsy: larger solid masses
excision: referral to general surgery or breast cancer
compare ultrasound, CT, MRI
Ultrasound: first line imaging
CT: radiation; good for staging cancer/lymph nodes
MRI: if abnormal US/ preferred in pregnancy; great imaging
- ultrasound used to look at uterus anatomy (abdomen)
- catheter placed into uterus, balloon inflated, sterile slaine pushed in
sonohysterography (SHG)
xrays taken evaluates inner uterus (polyps/fibroids)
evaluates uterus shape
spillage of dye into abdomen- fertillity
hystersalpinogogram (HSG)
closes the vagina- by shortening/narrowing prolapse
Lefort Colpocleisis
- utilized for stress urinary incontincence
- small piece of mesh inserted below the urethra
- usually used in women with hypermobile urethras- if they cough they pee
transvaginal taping
- performed with abnormal pap smears
- suspicious lsions on cervix/ulcer
- green filter allows abnomal cells to show up white
colposcopy
after a colposcopy pathology reveals (CIN I, II, III, cancer) what is the next step
*If CIN-pt will repeat pap smear in one year; if still abnormal will have to do colposcopy again
if CIN II OR III automatically get LEEP
LEEP (loop electrosurgical excision procedure)
- performed in the OR under anesthesia typically
- removes outermost portion of the cervix
- discharge for weeks, scab may form and fall off around 6 weeks post op
- avoid tampon until healed
- repeat paps every 3 months until 2 normal in a row
-occasionlyy LEEPs need to be repeated
LEEP (loop electrosurgical excision procedure)
- “freezing” abnormal tissue
- can cause pain initially, discharge for weeks, possibly later
- no tissue taken and less precise
- only used for LSIL and young patient preserving cervical length
cyrotherapy
what can be done for incorrectly placed IUDs?
hysteroscopy
exploratory laparascopic surgery
- camera inserted through cervix into uterus
- ability to remove polyps/fibroids via direct visualization
- performed in either clinic or OR
hysteroscopy
- performed with postmenopausal bleeding with endometrial lining >4mm
- takes small sample of endometrial tissue
- insert curette thru cervical os
endometrial biopsy
- performed with postmenopausal bleeding with endometrial lining >4mm
- takes small sample of endometrial tissue
- insert curette thru cervical os
endometrial biopsy
